The letters were postmarked prior to the Boston bombings so the two attacks are unrelated. But everything else about this case is bizarre.
The Blaze has extensive background on the suspect, Paul Kevin Curtis, who has a history of mental illness and minor law breaking.
Fox News has some of the weird details:
Curtis believed he had uncovered a conspiracy to sell human body parts on the black market and sometimes performed as an Elvis Presley impersonator, the Associated Press reported.
The letters to Obama and Wicker said: "To see a wrong and not expose it, is to become a silent partner to its continuance." Both were signed, "I am KC and I approve this message."
Ricky Curtis, who said he was Kevin Curtis' cousin, said the family was shocked by the news of the arrest. He described his cousin as a "super entertainer" who impersonated Elvis and numerous other singers.
"We're all in shock. I don't think anybody had a clue that this kind of stuff was weighing on his mind," Ricky Curtis said in a telephone interview.
Ricky Curtis said his cousin had written about problems he had with a cleaning business and that he felt the government had not treated him well, but he said nobody in the family would have expected this. He said the writings were titled, "Missing Pieces."
Multiple online posts on various websites under the name Kevin Curtis refer to the conspiracy he claimed to uncover when working at a local hospital from 1998 to 2000.
The author wrote the conspiracy that began when he "discovered a refrigerator full of dismembered body parts & organs wrapped in plastic in the morgue of the largest non-metropolitan healthcare organization in the United States of America."
Well, at least he wasn't a right wing nut, right? Just your garden variety, everyday sort of nut. Anyone on the left who tries to tie this guy to the right will look even more foolish than when they tried to portray Jared Loughner's attack on Gabby Giffords as the result of a bullseye map of targeted congressional races posted by Sarah Palin.
I'd love to know where he got the ricin, if he made it himself, or was able to buy it from somewhere or somebody. Beyond that, we can be thankful for the vigilance of postal workers on the Hill.
